钢化玻璃冲击波毁伤实验中的碎片规律研究

为了研究钢化玻璃受到冲击波作用破坏后产生的玻璃碎片造成的次级毁伤效应，针对6 mm、10 mm和15 mm三种不同厚度的钢化玻璃分别开展了多发外场化爆实验.实验对玻璃碎片的尺寸分布、飞散距离分布和碎片最大飞散速度等情况进行了数据收集和统计.通过对碎片的尺寸分布、飞散距离分布等的实验统计数据进行分析研究，给出了其分布规律和特点.根据实验记录的碎片最远飞散距离，利用平抛运动公式估算了碎片最大飞散速度，并验证了估算结果的准确性.实验结果表明，玻璃碎片的最大飞散速度均在11 m/s以上，最大速度可以达到25 m/s以上.

Fragments Regularity Research on the Shock Wave Damage Effect Experiments of the Tempered Glass

In order to investigate the secondary damage of the glass fragments of the tempered glass subjected to blast shock waves, several explosion experiments were performed on the tempered glass with the thickness of 6 mm, 10 mm and 15 mm, respectively. In the experiments, data collections and statistical work of the size distribution, the splash distance distribution and the maximum splash velocity have been done. According to the experimental results, the size and the splash distance distribution of the glass fragments were analyzed, and the regularity and characteristics of the distribution were proposed. Meanwhile, with the fragment maximum splash distance recorded in experiments and the equation of the flat parabolic motion, the maximum splash velocity of the fragments was estimated, which agrees well with the results of the reference. Experimental results show that the maximum splash velocities of the tempered glass subjected to blast wave in all experiments were larger than 11 m/s, in which the largest one was above 25 m/s.
